#
# MODE defOpt_fPIC configuration
#
# WARNING: Do not edit this mode unless you know what you are
#          doing. It's required to build Zlib.
#
# Usage: - Apply optimization string to each variable
#        - "unset" will cause the variable to be not set
#          instead of just set to null.
#
# Use this as an example for defOpt_myMode combined modes
